mpisync — Open MPI timing tools

SYNTAX

mpisync [options]

mpirun_prof [options]

ompi_timing_post [<timing-file>] [<processed-file>]

DESCRIPTION

mpisync : determines clock offsets relative to Head Node Process (HNP). It accepts the following options:

	•		-o , --output : The name of output file where offsets related to HNP will be written
	•		-h , --help : Print help information

ompi_timing_post takes the timing output file as input parameter. The events are sorted by the timestamps. Next, the timestamps are replaced with time offsets relative to the first : previous event.

mpirun_prof is a wrapper around mpirun that performs clock synchronisation and post-processing of the timing output file.

NOTES

The mpisync code was derived from MPIPerf project: - http://mpiperf.cpct.sibsutis.ru/index.php/Main/Documentation

FILES

The output file has following format:

<hostname> <round-trip-time> <offset-from-hnp>
